The Titanoboa was a 900kg, 15m long snake that lived 58 million years. Scientists thought it couldn't exist. Yet they discovered its fossil in Cerrajón, Colombia. She, a constrictor that could kill anything with a pressure of 28kg per square centimetre. That's the equivalent of being under three Eiffel Towers.
The people at Smithsonian Magazine asked who would win a battle between the Titanoboa and the most famous megacarnivore of the Cretaceous Period -- 67-65.5 million years ago -- the six-tonne Tyrannosaurus Rex.
Both lived in different places, but that didn't stop them to imagine such an epic battle. [Smithsonian Magazine]
